SEL-2414 Transformer Monitor Instruction Manual Date Code 20130214
Installation
Card Configuration
Voltage Card (3 AVI)
Supported in Slot E only, order this card when you have either four-wire wye-
connected PTs or open-delta connected PTs. With a voltage card installed, the
SEL-2414 tracks the frequency (using positive-sequence voltage) and samples at
4 times a cycle—see Sampling and Processing Specifications on page 1.10 for
more information.
NOTE: The device tracks the
frequency if 3V1 is greater than 0.75 V.
Current/Voltage Card
(3 ACI/3 AVI)
Supported in Slot E only, order this card when you have three-phase CTs and
either single or three-phase (wye or delta) PTs needed in a single slot. Secondary
phase current ratings are 5 A rated. Voltage ratings on the PTs support three
(300 Vac) inputs. With a current and voltage combination card installed, the
SEL-2414 tracks the frequency (using positive-sequence current) and samples at
4 times a cycle—see Sampling and Processing Specifications on page 1.10 for
more information.
Current Card (4 ACI)
Supported in Slot Z only, this card provides current inputs for three-phase CTs
and one neutral CT. Secondary phase current ratings are either all 1 A or all 5 A;
you cannot order a combination of 1 A and 5 A phase CTs on one card. However,
the phase CTs and the neutral CT can be of different current rating. For example,
you can order three 5 A phase CTs and a 1 A neutral CT, or three 1 A phase CTs
and a 5 A neutral CT. With a current card installed, the SEL-2414 tracks the fre-
quency (using positive-sequence current) and samples at 4 times a cycle—see
